Neither the National Park Service
nor the North Carolina Historic Preservation Office promotes
or recommends any particular type of marker or plaque to
recognize National Register properties, nor are there any
requirements regarding inscriptions for such plaques. Owners
of National Register properties may purchase at their own
expense a marker or plaque from one of several
manufacturers. Several of the following manufacturers are
listed in The
Old House Journal Catalog as suppliers of custom and
generic markers for National Register properties. Owners may
contact these companies directly for product information.

Service posting for additional plaque manufacturers and
suggested wording for National Register plaques: www.nps.gov/nr/faq.htm#plaque.
